This invention relates to a resilient mounting and more particularly to a mounting adapted to dampen out vibrations be tween a member such as an internal combustion engine and its support.

An object of the invention is to provide an inexpensive mounting of elastic material which is subjected to a tension.

Another object of the invention is to p'o or disassembled.

Other objects and advantages will more fully appear-from the following descriptlon taken in connection with the accompanying drawings in which:

Fig. l is an end view of an internal combustion engine showing the :frame members of an automobile chassis in section.

Fig. 2 is. a plan view of the mounting,

parts bein broken awa andin section, showing a slig tly modifie form of my invention.

Fi 3 is a side view of Fig. 2, the frame mem r being in section.

In the mountin of an internal combustion engine in a vehic e frame it has been' found that it is necessary to have a. certain amount of stabilit in a direction transverse to the engine an frame, and at` the same time to absorb vertical and fore and aft vibration of the engine relative to the frame. I have provided a. mounting of the type which can be designed for any engine to give the necessary flexibility in one direction and yet provide a given stability, independent of the necessary flexibility in another direction.

Referring to the illustrated embodiment of my invention,'l have shown an interna-l jectin arms 12. Frame members 14 have been lustrated as the frame members of an automobile chassis adapted to form the suppgert for the engine 10. A stamping 16 has n shown secured to the arm 12 and is adapted to receive at its outer end a connection which comprises an important part of my invention. A rubber member 18, shown in the form. of a pad, has its opposite facesv provided with metallic plates 2() and 22 which are vulcanized thereto. The plate 20 is secombustion engine 10 having laterally procured to the stamping 16 in an convenient unit and an aperture 28 has been provided Y to receive the rivets 24, the heads of which en ge the plate 20.

n Fig. 1 I have shown the mounting as supportin the en ne 10 solely through the ru er a 18, the atter being under tension. Hereto ore rubber blocks or supports have been used to insulate the engine from the frame but as these blocks have been under compression they do not eliminate small vibrations set up by the motor because the blocks are com ressed.

By securing t e engine to the frame through an elastic member the support is more resilient and the small vibrations are eliminated.' It will be understood that the entire weight of the motor as shown in Fig. 1 will be supported through the rubber mounting ywhich is under tension.

In Fig. 3 I have provided the plate 20 with an inwardly turned flange 30 adapted to engage a resilient member such as a rubber block 32. The rubber block is supported on the lower flange of the side frame member 14 and is adapted to takea portion of the engine load. This block is intended for use only when a heavy load is to be sup orted and there is danger of the rubber mem er 18 tearing apart. However, it is to beunderstood that under certain conditions the rubber member 18 is suicient to support a normal load.

It will be understood that as the rubber members are under tension, by the weight of the engine, horizontal movement of the latter is restricted more as the rubber members are more dense and solid than the usual rubber mounting due to the rubber members being under tension.

It will be obvious that various changes may be made in the arrangement, combination and construction of the various parts of my imusV proved device without departing from the spirit of my invention and it is my intention to cover by my claims such changes as may reasonably be included within the scope thereof.

W'hat claim is:

l. In combination, a plate like rubber member, a plate like metallic member bonded to each of the opyosite faces of said. rubber member forming a mounting unit? means for securing to one of said metallic. meiL bers a part or an internal combustion enginea means for seeuring the other metallic member to' a chassis frame, said rubber memberv being held under tension by the load of said engine and resisting horizontal movement of said engine throughout its area by resistance to compression of the rubber member.

2. In' Combination, a plate like rubber member, a plate like metallic member bonded to each of the opposite faces of said i" "ver member forming a mounting unit, means or securing to one of said metallirJ members vibrating mass, and means for securing the other metallic member to a supporting ber, said rubber means supportm; said brating mass by tension on said rub er member and r. ising horizontal movement of said vibL lg mass by resisten-ee to erompression throughout the bonded area of the rubber 'with the metallic plates.

3. ln combination, a plate like rubber member, a plate like metallic member be to each of the opposite faces member forming mounting mntv m securing; to one of said metallic memb part of an internal combustion en ine securing the other metallic member to chassis trame, said rubber member resi,

,. n o, ension me vertical rorees or said enf and resisting by compression tie originen bonded area of said rubber memberuthe non :conta-l forces of said engine.,

In combination, a plate like T111bbmember, a metallic member bonded to or fa of said rubber member, a metalli@ me' b bonded to tbe opposite face of said i b member, a vibrating weight secured to e f said plates, a support secured to the other said plates, said rubber member resisting ver tical and longitudinal movement of said. Weight through tension only on said .rr-.rbbv 1 and resisting transverse movement on said weight through compression only.

5. In combination, a motor vehicle engine and frame, a plate like non-metA `lie member held under elastic tension between the eng and the frame and serving to eonneot tl" said non-metallic member resisting vorti vibration of said engine through tension o said non-metallic member and resisting hoz zontal movement of said engine by resistentie to compression throughout the area of said.

non-metallic member.
